An easy way is: <table><tr> <td> <!-- Column 1, with Adsense Code --> <script type="text/javascript"> ... </script> </td> <td> <!-- Column 2, with Adsense Code --> <script type="text/javascript"> ... </script> </td> </tr></table> Code (markup): You can do it with CSS and divs only too, but IMO this method will be easier for you.
you can do it one BELOW the other just by putting the code one below another. you can also do it side by side, one NEXT to each other. the way you can do it is by creating a table with 2 column and put the code in each column
